I have following configuration in the application that works perfectly fine with queues and redelivers the messages when a RuntimeException occurs with transaction rollback as expected.
But the same configuration fails to redeliver message with topics and emits following warning message:
WARN DefaultMessageListenerContainer - Setup of JMS message listener invoker failed for destination 'XXX_TOPIC' - trying to recover. Cause: JTA transaction unexpectedly rolled back (maybe due to a timeout); nested exception is javax.transaction.RollbackException: One or more resources refused to commit (possibly because of a timeout in the resource - see the log for details). This transaction has been rolled back instead.

The Spring version used is 3.1, ActiveMQ 5.14, Atomikos 4.0.6.
Please let me know if i missed any configuration for topic DMLC.
(I hope this below makes sense, I had a bit of a struggle with formatting).
We have an application (currently being refreshed from technology of circa 2005) whose owners require the use of Oracle AQ for message handling.
We are using the Spring JDBC extensions, and when the application begins to listen to the queue it gets a ClassCastException saying "X cannot be cast to oracle.jdbc.internal.OracleConnection".
Where X is either a WrappedConnectionJDK7 from jboss when we use a datasource defined in Wildfly e.g.
<bean id="dataSource-supsrep"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#localhost:1521:XE" />
<property name="username" value="...." />
<property name="password" value="...." />
</bean>
or X is a PoolGuardConnectionWrapper from commons.dbcp when we define the datasource like this:
<bean id="dataSource-supsrep"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#localhost:1521:XE" />
<property name="username" value="...." />
<property name="password" value="...." />
</bean>
Message Listener bean is defined like this :
<bean id="messageListener" class="xxx.report.dispatch.DispatchMDB" />
Message Listener container bean is like this :
<bean id="reportProcessorXslfoHigh"
class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="sessionTransacted" value="true" />
<property name="connectionFactory" ref="AQconnectionFactory" />
<property name="destinationName" value="Q1_XSLFO_HIGH" />
<property name="messageListener" ref="messageListener" />
<property name="transactionManager" ref="transactionManager" />
<property name="concurrentConsumers" value="1" />
<property name="maxConcurrentConsumers" value="1" />
<property name="receiveTimeout" value="30000" />
<property name="idleTaskExecutionLimit" value="30" />
<property name="idleConsumerLimit" value="1" />
</bean>
The connection factory is like this :
<orcl:aq-jms-connection-factory id="AQconnectionFactory"
data-source="dataSource-supsrep" native-jdbc- extractor="oracleNativeJdbcExtractor" />
and it uses a Native JDBC Extractor :
<bean id="oracleNativeJdbcExtractor"
class="org.springframework.jdbc.support
.nativejdbc.OracleJdbc4NativeJdbcExtractor" />
So my question is - can this be overcome by Spring configuration details - or is there another way round it? Clearly the underlying connection is needed but after 3 days of research I cannot see how it can be done.
Any clues gratefully received !
Thanks,
John
Using MySQL workbench I can connect to the cluster db without any issue. but when I use it as the connection string jdbc:mysql:loadbalance://node_ip1,node_ip2,node_ip3/cluster_db_name?loadBalanceBlacklistTimeout=5000&loadBalanceStrategy=bestResponseTime from the app it will give me an error saying connection timeout. After that I use one cluster node and try to connect to it as we connect to localhost jdbc:mysql://cluster_node1/cluster_db_name?relaxAutoCommit=true&autoReconnect=true&useUnicode=true&connectionCollation=utf8_general_ci&characterEncoding=utf8&characterSetResults=utf8 but it also gives me the same error.

I am getting the error:

The last packet successfully received from the server was 989,906
milliseconds ago. The last packet sent successfully to the server was

Checked many blogs , but not getting proper solution , my db is in same server .
Any idea?
I think this is due to NoRouteToHostException. That case for the network configuration state. Look this and those

please advise why i get this error, and how to fix it, thanks.
Try using the org.springframework.orm.hibernate4.HibernateTransactionManager
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="dataSource" ref="dataSource" />
<property name="sessionFactory" ref="sessionFactory" />
</bean>
